First embodiment
As shown in Figure 1, the method for the recovery inertial sensor working condition of first embodiment of the invention, is applied to mobile whole
End, comprising:
Step 101, obtain mobile terminal in inertial sensor condition discrimination parameter.
The inertial sensor that can be set in the terminal include but is not limited to be acceleration transducer, gyroscope,
Acceleration and the two-in-one sensor of gyroscope etc..Therefore, different types of inertial sensor, the condition discrimination parameter obtained herein
It is different.
When inertial sensor is acceleration transducer, condition discrimination parameter refers to acceleration transducer at any one
Or the acceleration value in multiple reference axis.At this point, this step specifically: obtain acceleration transducer in any one or more seats
Acceleration value on parameter.
When inertial sensor is acceleration transducer, condition discrimination parameter refers to the angle speed of angular movement detection sensor
Angle value.At this point, this step specifically: obtain the magnitude of angular velocity of angular movement detection sensor.
Step 102 determines whether the working condition of inertial sensor is normal according to condition discrimination parameter.
In embodiments of the present invention, the working condition for detecting inertial sensor mainly judges whether inertial sensor occurs
Due to mechanical silicon moiety mass block between, inertial sensor caused by sticking between mass block and silicon substrate loses
Effect.When failure occurs, inertial sensor working condition is abnormal.For whether failing, herein mainly by that will obtain
The condition discrimination parameter and preset reference value obtained is compared determining.
When inertial sensor is acceleration transducer, one can be preset herein for indicating that inertial sensor works
Acceleration range when state is normal.The acceleration range is expressed as [the second acceleration rate threshold, the first acceleration rate threshold].Its
In, the first acceleration rate threshold is greater than the second acceleration rate threshold.Since acceleration is divided into positive and negative, the first acceleration under normal conditions
Threshold value is the constant greater than 0, and the second acceleration rate threshold is the constant less than 0, and the absolute value of the two can be equal.
In order to improve the accuracy of judgement, when acceleration value is greater than the first acceleration rate threshold and acceleration value is greater than first and adds
When the time of threshold speed is more than first time threshold, inertial sensor operation irregularity is determined；And/or when acceleration value is less than
When second acceleration rate threshold and acceleration value are more than second time threshold less than the time of the second acceleration rate threshold, determine that inertia passes
Sense device working is abnormal.
Wherein, the first acceleration rate threshold and the second acceleration rate threshold can be arranged based on practical experience.The first time threshold
It can also arbitrarily be arranged with second time threshold, and may be the same or different.
When inertial sensor is angular-rate sensor, one can be preset herein for indicating that inertial sensor works
Angular velocity range when state is normal.The acceleration range is expressed as [the second angular speed threshold value, the first angular speed threshold value].Its
In, the first angular speed threshold value is greater than the second angular speed threshold value.Since angular speed is divided into positive and negative, the first angular speed under normal conditions
Threshold value is the constant greater than 0, and the second angular speed threshold value is the constant less than 0, and the absolute value of the two can be equal.
In order to improve the accuracy of judgement, when magnitude of angular velocity is greater than the first angular speed threshold value and magnitude of angular velocity is greater than first jiao
When the time of threshold speed is more than first time threshold, inertial sensor operation irregularity is determined；And/or when magnitude of angular velocity is less than
When second angular speed threshold value and magnitude of angular velocity are more than second time threshold less than the time of the second angular speed threshold value, determine that inertia passes

Time then illustrates 3-axis acceleration sensor operation irregularity.
It certainly, in a particular application can also be in the acceleration value in some or multiple reference axis not in this acceleration threshold
When being worth in range, it is believed that illustrate 3-axis acceleration sensor operation irregularity.
Here, since reference axis has a positive negative direction, acceleration be divided into it is positive and negative, so it is assumed herein that the acceleration rate threshold model
It encloses for [- 2g ,+2g].
Step 202, obtain 3-axis acceleration sensor preset coordinates axis on acceleration value.
In this, it is assumed that obtaining the acceleration value of the X, Y, Z axis of 3-axis acceleration sensor.
Step 203 determines whether the working condition of 3-axis acceleration sensor is normal according to the acceleration value of acquisition.If
Normally, then return step 202；It is no to then follow the steps 204.
Through comparing, if there is the acceleration value in 1 reference axis not within the scope of above-mentioned acceleration rate threshold and maintain it is this
Situation has been more than preset time (such as 2 minutes), then it represents that 3-axis acceleration sensor operation irregularity.With the acceleration value in X-axis
For, acceleration value is -2.2g and is maintained the time of -2.2g to be more than 2 minutes, then it represents that 3-axis acceleration sensor work
Make abnormal.If the acceleration value in 3 reference axis is all within the scope of above-mentioned acceleration rate threshold, then it represents that 3-axis acceleration sensing
Device is working properly.
Step 204 obtains shake control parameter.
Wherein, which includes vibration frequency and vibration amplitude, can be stored in advance in a storage module.Cause
This, obtains above-mentioned shake control parameter by reading memory module herein.
Step 205 shakes according to the shock module in shake control state modulator mobile terminal.
Here, shock module can be realized using motor.After starter motor vibration, the vibration stress of motor passes through mobile terminal
Mainboard or construction package be transmitted to 3-axis acceleration sensor, sticking for 3-axis acceleration sensor can be released by this stress
Failure.
Step 206, the vibration duration for obtaining shock module.
Step 207 judges to shake whether duration is more than vibration duration threshold value.If it does, then process terminates；If not yet
Have, then return step 202.
Wherein the vibration duration threshold value can be arbitrarily arranged.
